This is a precious jewellery, the sewing machine of my mum. Surely It is older than me and I'm very affectionate to it. I remember when I was a child, that I observed my mum's sewing clothes for all the family and also for me. Now I'm the one who continues to use it. But recentely it has some problems: when I do zig zag it makes a strange sounds and last time it stopped to sew!!! What can I do now? It needs of a overhaul, but I cant' stop sewing for so long time. I need of a solution....
